Assessment of Leg Volumes Leg volumes of both right and left legs from ankle to knee will be determined. This is done using a calibrated tape measure (Gulick-type) to measure circumferences at 4 cm intervals starting at the malleoulus and progressing toward the knee. From these circumference measurements, limb volumes will be determined using the well established truncated cone model together with a validated software algorithm. Using this method the wound assessor enters the circumferences into a standardized form and the appropriate volumes are automatically determined.
